COMBINED GAS AND COAL RANGE.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed December 17, 1919. Serial No. 345,481.

To all whom it may concern:

Be it known that we, F'REDERIC G. NIG- OLAUS and JOSEPH ROY, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Combined Gas and Coal Ranges, of I, which the following is a specification, refer-;.

ence being had therein to the accompanying" drawing.

This invention relates to improvements in combined gas and coal ranges, and pertain to a construction whereby either coal or gas the line of gmay be used aS a fuel separately, or both at vertically through the center of the oven that the gas burner can be placed immediately at the junction of the flue passage from the fire-pot with the downwardly extending oven surrounding flue, whereby the coal or gas burner may be separately or jointly used.

A further object of our invention is to provide a combined gas and coal range in which the flue from the fire-pot extends downward between the fire-pot and the oven, and thence around the oven and out at the top to the chimney flue, instead of having the flue, as heretofore, from the fire-pot pass horizontally backward over the oven, then down around its bottom and out to the chimney flue, whereby the burner can be placed immediately at the junction of the fire-pot flue passage with the upper end of the-downwardly extending oven flue.

A further object of our invention is to so arrange the oven and its surrounding flue that a suflioient space is provided above the oven for the usual four top cooking burners, without the necessity of extending the range frame, which extension is necessary in the common form of flue arrangement in combined gas and coal ranges heretofore constructed, whereby economy in space is effected, thus particularly adapting our combination range for the use in apartments where space is limited.

Further, by means of our improved flue arrangement, with the gas burner located as above stated, we are enabled to place the water coil or back at the inner side of the fire-pot against the outer wall of the downwardly extending flue, whereby the watercoil or back is heated either from the coal Fig. 4 is a perspective sectional view range embodying our invention.

Fig. 6 is a transverse sectional view of the burner on the line 6-6 of Fig. 5.

Fig. 7 is a perspective view showing the range housing broken away and the oven therein in perspective.

Fig. 8 is an end view of the right hand end of Fig. 1.

Referring now to the drawings, 1 is a range housin containing a fire-pot 2 and an oven 3. fn our im roved construction, we provide a downwar ly extending flue 4., which is located between the fire-pot 2 and the oven 3, thus spacing the two apart. The flue 4 continues around the bottom of the oven 3 b the horizontal extension 5 thereof, and t ence upward behind theoven by the vertical extension flue 6, and thence forward over the to of the oven by its horizontal extension 2, which has its forward end communicating with an outlet flue opening 8, which in turn communicates with the chimney flue 9. This arrangement provides a top burner receiving space 10 in which the usual four top burners (not shown) are placed. This arrangement, it will be observed, provides a space for the top burners within the rectangular range housing 1, without any lateral extension which is provided in the usual flue arrangement to accommodate the top gas burners.

The upper inner edge of the fire-pot 2 is provided with a flue passage 11, which communicates with the upper end of the downwardly extending flue 4, and placed within this flue passage 11, at its junction with the upper end of the flue 4, is "a suitable gas burner 12. This gas burner has a down- Fig. 5 is a detached inverted plan of the burner.

wardly extending as outlet or slit 13, which throws the Home downward into the upper end of the flue 4. A gas supply 14, communicates with the burner 12. his as sup- Jly 14 receives its gas from a suitab e maniold 15, which also sup lies gas for the four top burners (not shown? through controlling valves 16. The fire-pot is provided with any suitable form of grate 17.

The inner wall of the flue 4, is formed by the adjacent wall 18 of the oven 3, and this wall extends upward above the oven to the top of the range frame, as at 19, thus closing the forward end of the flue T and form ing a closed flue wall from the top of the range frame to the bottom of the oven. The outer walls of the flues 4 and extension 5, are formed bv a casing 20, and the upper or outer wall of the portion 7 of the flue is formed bv a suitable horizontal wall 21, the oven Wall forming the inner and lower walls 3' of the flue extensions 5, 6 and 7.

By means of our improvement we are able to provide a combined coal and gas range of a very simple construction, which, in practice, is found to be effective and also economical in space occupied thereby.

Referring now particularly to Figs. 4 and 7, it will be seen that the flues 5 and 7 pass around the oven, and that the ends 20 and 21 of the oven project beyond the walls of the fines 5 and 6.

The end wall 22 is bolted or riveted the adjacent wall of the range housing 1, shown at 23 in Fig. 8.

Having thus described our invention, what we claim and desire to secure by Letters Pat cut is 1. A combined coal and gas range comprising a housing, a fire-pot therein, an oven within the housing and spaced apart from the fire-pot forlnin a downwardly extendin flue communicating at its upper end with t e fire-pot, said flue extending around the oven and communicating at its outer up per end with the chimney flue, and a burner located at the top of the communication between the fire-pot and the up er end of the said downwardly extending flile the burner having a gas flame o ening toward the downwardly extendin ue.

2. A combined coa and gas range comprising a housing, a flrerpot therein, an oven within the housing and spaced apart from the fire-pot forming a downwardly extending flue, a water-back at the inner side of the fire-pot and against the outer wall of the said flue, the upper inner side of the fireot communicating with the upper end of l he flue, a gas burner located at the top of the communication between the flue and the fire-pot and having a downwardlyextending gas flame opening, said flue extending around the oven and having its outlet communicating with the chimney flue.

2%. A range comprising a housing, a firepot therein, an oven therein and spaced apart from the fire-pot, constituting a downwardly extending flue, the fire-pot having conununication at its upper inner side with the upper end of the flue, the flue extending around and over the top of the oven and having its outlet end communicating with the chimney-flue, a water back at the inner side of the fire-pot and against the adjacent wall of the said downwardly extending flue, for the purpose described and a gas burner at the juncture of the flue and fire-pot.

4. A combined coal and gas range, conr prising a housing, a iire'pot therein at one side, an oven within the housing and spaced apart from the iirwpot forming :l down wardly extending flue having its upper end communicating with the tire-pot, the flue ex tending around the oven and having at its end an exit flue opening, a gas burner located at the juncture of the downwardly extending flue and the fire-pot, the burner hav ing a downwardly projecting flame opening whereby the draft through the flue draws and elongateg the flame within the flue, thus adapting the range for either coal or gas fuel or both simultaneously.

5. A combined coal and gas range com-- prising a housing, a firepot therein, an oven within the housing an.l spaced apart from the fire-pot forming a downwardly extending flue, the upper inner wall of the flue closed from the top of the range to the top of the oven, the flue extending around the oven and having a chimney outlet communication, and a burner located at the upper end of the downwardly extending flue whereby the parts cooperate to produce either a coal or gas or combined coal and gas range.

6. A combined coal and gas range, comprising a housing, a fire-pot therein, an oven within the housing and spaced apart from the fire-pot forming a downwardly extend.- ing flue communicating at its upper end with the firepot, the upper inner wall of the flue between the top of the ran e and the top of the oven being closed, the no extending around the oven having a chimney outlet communication, the said surrounding flue being narrower than the oven, and a burner located at the upper end of the downwardly extending flue, the parts cooperating for the purpose described.

In testimony whereof we hereunto affix our signatures.
